Best Place in Montana to MTB

[PMcGuire]

My girlfriend and I are moving to Montana in June. We would like to know where are the best places to MTB?

If you are moving to Missoula, the blue mountains have great single track. There are some trails just south of town in East Helena. That is the extent of my experience in Montana. I would definitely hit up the local bike shops for more info.
